Originally used in basketball, often termed as lane violation.

For modern day use, it's for when you drop your food on the ground, but you say " 3 second rule!" as an excuse to say that your food remained clean.
"Yo hand me that juicy barbeque bacon burger"
"There you go bro.. *OH SHIT I DROPPED IT*"
"Pick that shit up, 3 second rule you remember?"

Get the 3 second rule mug.
The rule goes as follows...
"If a food item falls to the ground and you pick it up in less than 3 seconds, you can pick it up"
*Friend drops an entire pizza upside down*
